B58 Custom DME Calibration (G Series)

B58 Custom DME Calibration (G Series)



Transform your B58 G-Series vehicle with a custom DME calibration by fluent.tuned!  We incorporate years of track and dyno testing into all our tunes to ensure optimum power and smooth delivery coupled with unrivaled reliability.  Not only will the tune be optimized for the modifications of the vehicle and fuel being used, but also to the climate, intended use, and your personal driving style.


Everyone's car is a unique representation of themselves, and we believe the tune should be no different.  Want more aggressive throttle response? No problem! Want a different powerband? Sounds good! The kid in you wants some exhaust burbles or flames? Hey, it's your car!  We'll be happy to explain any risks associated with such requests and work with you to balance your goals with our expertise.


Expect the utmost attention during the tuning process and beyond.  Most revisions are turned around within hours, and will not exceed 24 hours unless under unique circumstances.  Communication will be efficient and any questions will be answered directly. 


OUR COMMITMENT - If our work load ever disallows us to maintain these qualities and timelines, we will temporarily mark all of our tunes as SOLD OUT to focus on providing the highest level of individualized attention that fluent.tuned is known for.  Our existing customers come first!


Experience a true custom DME Calibration by fluent.tuned!
